A new blog

There is a lot I like about Blogger. I've been using it since June 2006, and I'm mostly happy about the way it works.

But not completely happy -- there are a few things that are irksome, such as:

• No satisfactory way to get a cut tag into long posts. And I have a tendency to write a lot of long posts -- at least long enough that I need cut tags.


• No way of removing or renaming the images you have uploaded. At this time, the only way to delete an image is to delete the whole post.


• No good way of backing up your blog. I had a good, simple script using wget but since Google changed the layout of Blogger, it no longer works so well (or at all).


• Google seems to have a very flighty attitude to making Blogger available to third party applications. The original Blogger 1.0 API does not work with Blogger 2.0; the Blogger 2.0 Atom API is now being deprecated in favour of yet another API. No wonder I haven't been able to find an Linux app that can successfully communicate with Blogger.

So I have decided to experiment with another blog, over on Wordpress. That doesn't mean I'm abandoning Blogger for Wordpress immediately, or at all.

Family walking on all fours

National Geographic has an article about a Kurdish family where five out of the nineteen siblings in one family walk on all fours instead of upright.

Scientists who have studied the three sisters and two brothers insist that it is not a hoax.

Uner Tan, a Turkish neurophysiologist, has studied them and believes they are "evolutionary throwbacks" to our ancestors. A team of German scientists led by Stefan Mundlos believes they have found the precise gene which has knocked out their ability to walk upright.

It's not clear what they mean by "the" gene that controls bipedalism: walking on two legs successfully requires many features, both anatomical and mental, and knocking out just one of them will cause the whole system to break. To take an extreme example, it's hard to walk upright if you have no legs. Less extreme example: the move to bipedalism would have required changes to our hips and backs. Our backs are still not completely evolved to suit our upright stance, which is why people are prone to back problems. Comparing us to our cousins (gorillas, orangutans, chimps and bonobos) shows that we have significantly longer legs than they do, relative to our body-size. The evolution of bipedalism would have required all these features to evolve more-or-less in lockstep (albeit presumably in fits and starts), and it isn't credible that there is a single gene that controls them all.

Nevertheless, certainly there could be a single gene -- or many single genes -- that the lack of could disable bipedalism. If you remove the accelerator cable from a car, the car won't move, but that isn't to say that the accelerator cable is the thing that makes cars move forward.

After studying the family, the British evolutionary psychologist Nicholas Humphrey pointed out that the genetic mutation alone wouldn't be sufficient to cause the lack of bipedalism. He gives equal credit to a family that was accepting of the children's strange gait, and making no efforts to cajole them into standing upright. Sensible, so far. But then he goes on:

"This is for real," Humphrey said. "You only have to look at the calluses on the hands of the young man [Huseyin] to see he's been on his hands for a very long time."

Why single out Huseyin? Don't the other four siblings have calluses on their hands? And walking on your hands is hardly the only way to make them callused.

I don't have any specific reason to expect a hoax, but calluses on the hands of one of the five siblings is hardly a reason to give the all-clear. Nevertheless, in the absence of any specific reason to expect a hoax, I think it is worth treating it as genuine.

The behavior could potentially reveal much about our own evolution, Humphrey says.

"Here we've got a living example of how it might be for a member of our species to walk on four legs," he said.

Most experts assume that the quadruped ancestors of humans walked in a similar way to apes such as gorillas and chimpanzees.

But the Turkish brothers and sisters walk on only their wrists or the heels of their hands, with their fingers held off the ground, the researchers say. This position appears to have saved their fingers from damage; the sisters, for instance, engage in both crochet and embroidery.

Chimps, our closest living relatives, use their whole hands and fingers for walking.

"Chimpanzees basically wreck their fingers by walking on them," Humphrey said.

[...]

"I think this new evidence, suggesting that [early-human ancestors] walked on their wrists, is much more plausible and interesting," Humphrey said.

I question this completely. Chimpanzees wreck their fingers? Chimps have very good manual dexterity, I'd need to see some support for this astounding claim before accepting it.

But even if correct about chimpanzees, Humphrey's claim that the siblings walk only on the heels of their hands isn't supported by the evidence available. The article has one photo of four of the siblings walking. In it, you can clearly make out just two hands on the ground, and in both of them, the people are clearly using their entire hand, fingers and all.

(Click image for full view.)

The photographic evidence contradicts Humphrey's claim, and calls into doubt Uner Tan's conclusion that this is a viable model of pre-bipedal human movement.

If you try it for yourself, I'm confident you'll find that it is impossible to do what the researchers claim. With the heel of the hand, or the palm, flat on the ground, it is virtually impossible to bend the fingers back far enough to keep them off the ground. There's maybe a couple of millimetres give in the finger joints, and it is quite tiring. There are basically three ways of hand-walking: with open hands flat on the ground; on closed fists; or on the knuckles of the fingers, as apes do when knuckle-walking. I do not believe there is any evidence at all, either in anatomically modern humans or any plausible ancestor, for a mode of quadrupedal walking where the fingers are held up off the ground.

There is no doubt at all that human development is complex. The five siblings in question all display a range of congenital deficiencies, include mild mental retardation and lack of balance. It is absolutely possible that whatever genetic damage the five siblings have -- and it might be as little as a single gene -- could lead to them doing the "bear crawl" into adulthood.

But I am extremely skeptical that this gives us any insight into human evolution. For Uner Tan to describe this as "backward evolution" is as absurd as it would be to describe Tay-Sachs disease as backwards-evolution, or sufferers of Huntington's Disease as "evolutionary throwbacks" to an otherwise unsuspected ancestor. The siblings are clearly broken. They're not a throwback to "primitive Man". The most one could say is that, possibly, early pre-bipedal ancestors of human beings may not have had the gene which the siblings are missing. But that's not the same thing: if you rip out the computer chip from a modern Ford Fiesta you don't get a Model T Ford, you get a broken Fiesta.

(Unlike modern cars, biological organisms are astonishingly good at continuing to work with bits missing. As fragile as living things are, we're also incredibly resilient.)

The war on the unexpected

Bruce Schneier has a good name for the faux-war on terror the cowardly Chicken Littles have created: the War on the Unexpected. Anything different or unexpected must be a threat:

We've opened up a new front on the war on terror. It's an attack on the unique, the unorthodox, the unexpected; it's a war on different. If you act different, you might find yourself investigated, questioned, and even arrested -- even if you did nothing wrong, and had no intention of doing anything wrong. The problem is a combination of citizen informants and a CYA attitude among police that results in a knee-jerk escalation of reported threats.

This isn't the way counterterrorism is supposed to work, but it's happening everywhere. It's a result of our relentless campaign to convince ordinary citizens that they're the front line of terrorism defense. ...

The problem is that ordinary citizens don't know what a real terrorist threat looks like. They can't tell the difference between a bomb and a tape dispenser, electronic name badge, CD player, bat detector, or trash sculpture; or the difference between terrorist plotters and imams, musicians, or architects. All they know is that something makes them uneasy, usually based on fear, media hype, or just something being different.

The full article is well worth reading, and contains many links to actual cases of the most awe-inspiring stupid security "threats". None of the examples quoted above are made up.

In recent weeks:

• Concert-goers to an open-air concert in Perth were told that picnic blankets and rugs were prohibited as they were a security risk. Adding a note of the surreal, the tickets warned patrons not to bring "crocodiles or spears" to the concert.


• A blind calypso musician and his band thrown off a plane after another passenger complained they had been in high spirits earlier but were now sitting quietly.


• An orthodox Jew on a train was arrested after passengers panicked on seeing him praying while sitting next to a man wearing a turban.


• A Florida bomb squad called in to blow up a typewriter.


• Police evacuate everyone within a mile radius of some fake dynamite taped to the side of a house.
  
  (The comments on that story are interesting: in summary, it seems that the cops simply followed the Department of Transportation's guidelines, which seem to be massively over-cautious compared to the guidelines offered by the Department of Defense and usual practice for disarming known high-explosive bombs.

Earlier incidents in the war on the unexpected:

• An Australian pub patron thrown out by bouncers for reading a book called The Unknown Terrorist.


• A Canadian firetruck racing to a fire in New York was stopped at the US border for eight minutes while border officials checked the firefighters' IDs and the truck's licence plates.


• In 2005, a man in the UK who fell into a diabetic coma on a bus was shot twice with a Taser gun by police who feared he may have been a terrorist.

Are we feeling safer yet?

Copyrighting the pyramids

How crazy is this? Egypt has announced that they are copyrighting the pyramids, and intend charging royalties to anyone who copies them.

Zahi Hawass, the charismatic and controversial head of Egypt's Supreme Council of Antiquities, said the move was necessary to pay for the upkeep of the country's thousands of pharaonic sites.

"The new law will completely prohibit the duplication of historic Egyptian monuments which the Supreme Council of Antiquities considers 100 per cent copies," [Zahi Hawass] said.

...

However, the law "does not forbid local or international artists from profiting from drawings and other reproductions of pharaonic and Egyptian monuments from all eras - as long as they don't make exact copies."

"Artists have the right to be inspired by everything that surrounds them, including monuments," he said.

Asked about the potential impact on the monumental Luxor Hotel in the US gambling capital of Las Vegas, Mr Hawass said that particular resort was "not an exact copy of pharaonic monuments despite the fact it's in the shape of a pyramid".

If the copyright only applies to exact duplicates (that is, the same shape and materials inside and out) one wonders that the point of retroactively copyrighting something created more than four thousand years ago? Are there really that many people making exact life-sized duplicates of the Great Pyramid of Giza?

Another study criticising voting machines

Over the last decade or so, the American political machine has become rotten to the core with vote fixing, secret counting, lost votes and other "irregularities". (Those with long memories of infamous political bosses like William Tweed will see this corruption as a return to normality after a half century of relative honesty and transparency.)

As Bruce Schneier reports, more and more US states are realising just how bad the electronic voting machines are. Like California before them, Ohio has just published a massive study on voting machines and found that they are insecure, untrustworthy, vulnerable to malicious software and operator fraud, and easy to undetectably hack using simple tools.

Colorado has decertified most of it's electronic voting machines. California seems to be ready to do the same, and surely Ohio can't be far behind. In 2006, New Mexico changed to a paper ballot system. Unfortunately for every politician who understands about the risks, there's another who is either ignorant, in denial, or actively pushing for insecure voting systems ("all the better to make sure the right person wins, my dear").

In related news, it seems that Diebold -- not the worst of the bad bunch at all, merely the first to be caught -- is re-thinking their voting machine business.

And in other news, former staff at Sequoia Voting Systems printing plant have gone public with claims that in 2000 they were ordered to send inferior quality punched cards to West Palm Beach (Florida), purposely misprinted, so that the cards would fail and Sequoia could push it's more profitable touch-screen voting machines to the states.

Testing airport security

You're probably familiar with any number of ad hoc experiments where some journalist, law-enforcement officer or random clown successfully smuggles a gun or knife onto a plane, demonstrating the weakness of airport security.

These sorts of anecdotes make powerful memes, but what does the scientific evidence say about airport security?

According to a recent study by the Harvard School of Public Health, there's no evidence that X-raying carry-on luggage, taking off shoes and confiscating small items has prevented any hijackings or attacks.

The TSA defended the searches, claiming that they confiscated 13 million prohibited items in one year, "most" of which were cigarette lighters.

Bruce Schneier responded:

This is where the TSA has it completely backwards. The goal isn't to confiscate prohibited items. The goal is to prevent terrorism on airplanes. When the TSA confiscates millions of lighters from innocent people, that's a security failure. The TSA is reacting to non-threats. The TSA is reacting to false alarms. Now you can argue that this level of failures is necessary to make people safer, but it's certainly not evidence that people are safer.

The report in the British Medical Journal points out that widespread screening for threats to public health are usually only enacted if there is clear evidence that they work -- otherwise they do nothing to improve health and safety, but merely waste a lot of time and money for no gain:

With $6.5 billion spent globally on airport protection each year, the public should be encouraged to query some screening requirements – such as forcing passengers to remove their shoes, the researchers said.

"Can you hide anything in your shoes that you cannot hide in your underwear?" they asked.

The Silly Season

The Christmas/New Year period is traditionally known as the Silly Season. This year, the entire month of December has been not just silly but crazy. Not only have I been very busy at work with my normal doing-two-jobs-for-one-pay duty, but on top of it all we've moved offices.

Consequently my rostered day off went down the toilet. I've put in a lot of late nights, up to and including after midnight, in the period just before we moved, and Mrs. Impala and I spent most of a weekend painting the new office, thanks to the old tenants who decided that "make good" actually means "oh, nobody will notice that we haven't sanded down the repairs to the plaster, or repainted, or actually cleaned the carpet".

At least, the real estate agent didn't.

In no particular order, some things I have learnt:

• Catching a taxi in the city at 1am on a Friday night is not easy. There's a chronic shortage of taxis, and a chronic oversupply of drunks and clubbers.


• People (and by people I actually mean a group of five drunken twenty-something baboons men) will actually step out into the middle of the road and try to stare down on-coming traffic, forcing the taxi to come to a complete stop. Eventually, due to some variety of random Brownian motion, they eventually staggered around enough to leave a car-sized gap between them, otherwise I'm sure I'd still be there two weeks later.


• Having even a mildly sprained back really, really sucks. My heart goes out to those with serious back problems.


• My room in the new office is the one room that isn't detectably air conditioned, so while everyone else is complaining of frost bite and wearing woolly hats and gloves, I'm melting into a puddle. Why am I not surprised?


• After stripping the server room of all unessential servers and equipment, we were left with no fewer than thirteen servers. Thirteen. For a company of about a dozen staff.


• When Melbourne has rain in December, it REALLY rains. And when it does, traffic slows to a complete stop.

I'm hoping that with Christmas just around the corner, things will settle back down to normal soon.

Market failures

Slate has an article discussing the ways that Adam Smith's "invisible hand" of the free market can be very bad at providing goods and services that are outside of the norm.

This brings us back to Nike's new shoe. Foot Locker is full of options that fit me and most other Americans. But American Indians make up just 1.5 percent of the U.S. population, and with feet on average three sizes wider, they need different-sized shoes. If we had all voted in a national election on whether the Ministry of Shoes should make wide or typical-width shoes, we surely would have chosen the latter. That's why Friedman condemned government allocation. And yet the market made the same choice. If Nike's announcement looks like a solution to this problem of ignored minority preference, it really isn't. The company took too many years to bring the shoe on line, and according to the Associated Press, the new sneaker "represents less of a financial opportunity than a goodwill and branding effort."

The Wall Street Journal is reporting on a different sort of market failure: the ever-increasing gap between rich and poor. This might be defensible if the rich were getting richer and the poor richer too -- in fact I remember being suckered into believing this myth as a teenager, but as the WSJ explains, in fact the poor are getting poorer, the middle class are treading water to keep from sinking, while only the rich are moving ahead. America hasn't been so unequal since the 1920s.

If Rudy Giuliani is Ras Al Ghul, is John Edwards Batman?

Ezra Klein suggests that Rudy Giuliani is really Ras Al Ghul:

Our society has reached its peak of decadence, imperialism, and corruption. By appealing to those worst excesses of the American psyche, Giuliani will get elected, and blow up the world, thus wiping our unsalvageable civilization from the map, and bringing the global order into balance. In other words, Rudy Giuliani is really Ra's Al Ghul. Discuss.

Over at Making Light, Teresa Hayden writes a long post about Giuliani. If you thought he was the hero of September 11, "America's Mayor", you couldn't be more wrong: Giuliani is the classic example of the incompetent, selfish, arrogant politician gaining political rewards for dealing -- badly -- with the problems that he himself caused in part.

Most people don't realise just how much of the disaster that was 9/11 was caused by Giuliani's decisions, starting with his decision -- against the advice of anti-terrorism experts -- to site the Emergency Command Centre in the World Trade Building, in a building that had already been attacked, so it would be convenient to City Hall. A nice short walk for Rudy.

There's more, much more. No wonder the New York firemen blame Giuliani personally for the deaths of so many of their fellows:

On 9/11 New York was left without an emergency command center because Giuliani, going against the advice of both the police and fire departments, decided to locate the center conveniently near City Hall in World Trade Center building 7, along with tanks containing tens of thousands of gallons of diesel fuel—in direct violation of New York City fire laws. This was despite the 1993 WTC bombing that proved it to be the number one terrorism target. It was this decision that put him on the street on 9/11 instead of inside a command center coordinating operations. Ironically, this also put him in front of hundreds of media cameras, sparking his image transformation into a “hero.”

While our “hero” was posing for the cameras, however, there was no communication possible between the police department and the fire department, whose REAL heroes were rushing to their deaths inside the towers. And there was likewise no communication between the police officers who identified an open stairway for escape from above the fire zone and the 911 phone operators who were telling soon-to-be-dead office workers to stay put and wait for the firefighters. Giuliani had been aware of the inadequacy of the emergency services’ communications equipment for many years, but did absolutely nothing about it. This criminal negligence also doomed hundreds of firefighters that were unable to hear orders to evacuate the north tower prior to collapse.

Whatever possibility existed for communication between the police and fire departments, whose radios operated on different frequencies, evaporated when Giuliani visited a makeshift fire/police command center that had formed in his absence. There he ORDERED THE POLICE BRASS TO LEAVE and accompany him uptown. This “heroic leadership” effectively put the fire department and police department commanders in different physical locations with no communication possible between them.

Present Police Commissioner Ray Kelly stated that he doesn’t have any idea who was in charge on 9/11 because Bernie Kerik and all the top chiefs in the police department basically acted as bodyguards to Giuliani and no one was running the shop.

Those wacky Republicans

It certainly seems to be a pattern... Republican politician makes a career out of discriminating against gays, then gets caught in some sordid, dirty, anonymous tryst with another man.

Last time it was Bob Allen; before him it was Larry "Wide Stance" Craig; and now, Representative Richard Curtis -- what is it with men with a personal name as a surname? -- finds himself in a gay sex extortion scandal after allegedly promising a young man $1000 for unprotected sex, then claiming he only had $100.

Curtis denied he paid the man for sex, and said he had given him gas money.

Now, I don't really care what body parts people insert in other body parts, so long as everybody involved is a consenting adult, but this is newsworthy because Curtis has a history of voting against bills giving homosexuals equal protection under the law: in both 2005 and 2006, he voted against granting civil rights protections to homosexuals, and then in 2007 he voted against a bill creating domestic partnerships for same-sex couples.

Update: Tom's Modern World has a good cartoon covering my thoughts on this issue:

Making Communist Yugoslavia look good

It's certainly very special when the Home of the Free makes Communist Yugoslavia under a despotic totalitarian government look good, but the experience of photographers in the USA is doing that.

Avram Grumer explains:

Back in the ’80s, my parents (who are Balkan folk dance enthusiasts) visited what was then the Socialist Federal Republic of Yugoslavia, a Communist nation. While there, my father photographed a picturesque lake. He snapped off a shot or two, and was interrupted by a government official who told him that photographing that lake was forbidden, due to the presence of some militarily sensitive facility (I forget what; a power plant or something). My father put the camera away, and that was it. They didn’t confiscate the camera or the film, didn’t make him expose the roll to the light, didn’t haul my parents off for an interrogation. A print of the photo hung on my parents’ wall for years; no sort of industrial facility is visible in it. It’s just a photo of a pretty lake.

Compare that with the treatment this Japanese tourist got at the hands of Amtrak and the New Haven police:

The Japanese tourist was ordered by a conductor on an Amtrak train from New York to Boston to stop taking photos of the scenery "in the interests of national security", and threatened to confiscate his camera. The tourist, who spoke little English, complied with the order and put the camera away in his bag. Nevertheless, at the next stop, the train was bordered by police, who threatened to remove him with force:

The police speak through the interpreter, with the impatience of authority. [...] The officers explain, “After we remove him from the train, when we are through our investigation, we will put him on the next train.” The woman translates. The passenger replies, “I’m meeting relatives in Boston. They cannot be reached by phone. They expect me and will be worried when I do not arrive on schedule.” “Our task,” the police repeat, "is to remove you from this train. If necessary, we will do so by force. After we have finished the investigation, we’ll put you on another train.” The woman translates. The traveler gathers his belongings and departs.

To add insult to injury, it turns out that Amtrak has no such policy prohibiting photography on their trains.

The witness to these events wrote:

It doesn't take more than five minutes, in any airport in this country, before I hear the loudspeaker, "The current terror threat is elevated." We hear “terror” endlessly – traveling, at home, on television, in the news. Recent political campaigns have reminded – no, badgered – us, to be very afraid. What did Franklin Roosevelt say, that “the only thing we have to fear is fear itself.” Terror. Paranoia. We can no longer differentiate between terrors. Is this our generation’s enlightened contribution to American culture?

Watching police escort a visitor off the train, I felt anger, not comfort. This action was beyond irritating. It is intolerable, unacceptable. If it bothered me, it paled in comparison to the way it inconvenienced, and will long trouble, this visitor to our country. We disrupted his travel plans and family reunion. Even greater than the psychological damage we inflicted is the harm we’ve done to ourselves. We missed an opportunity to show kindness, to be ambassadors of goodwill. The visitor will return home. He will indeed impress many people – not with pleasant memories and pictures of a quiet morning trip along the New England coast, but with a story of being removed and detained by American police for taking pictures. Do we imagine we’ve gained anything because a single visitor returns home with stories of mistreatment?

Such blatant attempts to intimidate photographers aren't limited to tourists or Arabs. Avram Grumer links to a number of sites documenting these incidents. At one of these sites, "C.E." explains that he's been a professional photographer for thirty years, been taking photos all over the world, during martial law, before and after military coups and terrorist bombings, and even once accidentally inside a military base, and he's never been subject to as much harassment as he receives in the USA. And he is an American.

I think the best, or at least the most amusing, comment explaining why these events are becoming more common came from Chris Waller, talking about the similar situation in the UK:

Increasingly in Britain a lot of overweight young men of low intelligence who are otherwise unemployable are being stuffed into ill-fitting uniforms and given the idea that they are saving the Western world from sinking into chaos as a result of terrorism.

Follow that spam!

Make Wade over at the CA Security Advisor Blog decided to find out what happens when you buy from a spammer.

Our journey begins outside of Washington, DC. I am sitting at my desk, going through my SPAM filtered email, when I see one that catches my eye, “Dreams can cost less repl1ca w4tches from r0lex here”. Sounds interesting I thought, and I could use a new watch. Knowing the harmful effects of opening unsolicited email, I decided to open the email in a controlled virtualized environment.

It seems that the spam most likely originated in a small church in Washington State, probably from a malware-infected computer used by Cheryl Neff, the assistant to the senior pastor. Mark followed the link in the email to a professional-looking, but temporary, website. Using a credit card opened specifically for the experiment, he then purchased a set of earrings for $77 including postage and handling.

Mark followed the money, from websites in China and Korea, through a series of shell companies starting in Las Vegas, and finally ending up in Cyprus where the money was collected. Surprisingly, the earrings may have been shipped from China, but if they were, they got lost in the mail, because the parcel never arrived.

I'm fascinated by the fact that spammers can actually find any buyers at all. Economists will often talk about trust issues. For example, banks tend -- or at least they used to, before the economic rationalists moved in -- to go for big, imposing, expensive buildings, with high ceilings and marble floors and Grecian columns as far as the eye could see. The more risky the industry, the more important to convince people that you are trustworthy by showing commitment. "You can trust us not to take your money and run, because we've invested a lot in this business and we won't be going anywhere for a long time". And yet this seems to go right out the window when it comes to on-line purchases, at least for those who buy from spammers. Most spam websites are active for only a few weeks, before they are close down and re-open under a new name. But there seems to be an never-ending stream of buyers.

It's tempting -- oh, so very, very tempting -- to just put it down to pure, unadulterated stupidity. But that's a simplistic answer. Many buyers are hardly stupid: they have good white-collar jobs, educations, can walk and chew gum at the same time.

So what's going on? Is it that buyers are so naive that they can't recognise that they're being scammed? Is spam just the 21st century version of the old con of selling the Brooklyn Bridge to some country bumpkin, still with hayseed in his hair, visiting the big city for the first time?

I think there's more to it than that. For various reasons (advertising, welfare, the legions of pop-psychology books...), we live in a society that encourages a sense of wishful thinking, that wanting something to be real makes it real. Not that Homo sap needs much encouragement to wishful thinking and delusion. Rather than "if it seems to good to be true, it probably is", too many people act as if "if it seems too good to be true, it will be true anyway just because you deserve it".

Add to that the widespread use of credit cards, which encourages people to act as if money didn't matter even when it does, at least until all five of your cards are maxed out. Since you're not really paying for the goods, the credit card is, the risk is minimal -- or so seems to be the perception.

But one thing that doesn't make any sense to me at all is that people can take seriously any advertising written as shoddily as "repl1ca w4tches from r0lex here". This is worse than Greengrocer's Apostrophe; worse than VCR instructions translated into English from Chinese by a Korean. Not only does it look careless and incompetent, it is a deliberate attempt to bypass software that filters out spam. That screams "Deceit!". Why would anyone choose to buy from somebody who as good as says "Hey, I'm lying to you right now"?

They make it hard to do the right thing

Studies into file-sharing patterns at American universities repeatedly show that the major factor involved is less price and more convenience. It's often been said that you can't beat free, but in fact you can: it's worth paying something for fast, reliable, good service.

There aren't a lot of television programs I watch, but there are a few. I have most of them on DVD box sets, but for the couple remaining, what to do? I for one would never Break The Law, but it gets tiresome watching the latest episode of Heroes by remote viewing: psychic powers are notoriously fickle and unreliable, and can sometimes be slow and flakey.

So I was very excited to receive an email from Amazon telling me that, as somebody who had purchased the Heroes Season One DVD, I might be interested in purchasing Season Two episodes for just ninety-nine cents. Would I ever -- with the current exchange rate, that's around the "sweet spot" that I'd be prepared to pay for Internet downloads.

Alas, it is not to be. They don't want my money:

Before you can download your Unbox video, you need to install the Amazon Unbox video player. ... Currently, the Unbox video player only works on PCs running the Windows XP operating system (see all system requirements) and is only available to our customers located in the United States (see all terms of use).

This is wrong in so many ways...

• There are standard, open formats for video that are viewable on any computer fast enough to deal with video. Your old Apple II won't make the cut, but there's no technical reason for restricting users to only people using Windows XP.


• Bittorrent and other file sharing technologies don't restrict users to those in the United States. If the studios want to compete, they better start learning that the marketplace is now global: 95% of potential viewers are not in the USA.


• Don't try to lock people into your shoddy, proprietary technology: I expect to use the browser and video player of my choice (within reasonable technical restrictions) to watch the videos.

Get with the program guys. You can compete with free, because people do want to pay for the videos they watch. You just have to make it easy for them to give you money, and provide a good service.

Internet tutorials

Justin a.k.a. _harlequin_ on LiveJournal rants the good rant about technical Internet tutorials:

I've been reliving this experience recently by trying to learn to program AVR microcontrollers in C from internet tutorials for "beginners", written by adults with mental capabilities similar to those of the ten-year-old, who hadn't yet grasped the concept that beginners (funnily enough) don't have an expert’s vast array of existing expertise.
It’s cute in a ten-year-old. But coming from an adult, it makes you want to hit them.

Adding insult to injury, they focus on explaining the obvious as if you are a moron rather than a beginner, whilst being completely oblivious to the number of advanced, unexplained steps they unthinkingly used to get there. If these people wrote cooking tutorials, they would go something like:

First, we start with some flour. This is flour [example of flour]. It is white and powdery. You can buy it at a place called a "shop", or a "supermarket", trading for it using a thing called "money". Next, the muffins come out of the oven, cooked and ready. You tell when they are baked correctly because they are brown. Not too brown [example of too brown], and not too light [example of undercooked muffin], just right.

And now you know how to make muffins!

SOMEONE SLAP THIS IDIOT!

Thanks to Mrs Impala for pointing me at this one.

Secrecy is like a weed

Unless you take steps to keep it under control, it spreads and takes over everything.

The Bush government has been one of the most secretive ever, for less reason than ever before. This stain has started spreading to even scientific organisations like NASA, which has refused to release the results of a survey into airline safety.

Anxious to avoid upsetting air travelers, NASA is withholding results from an unprecedented national survey of pilots that found safety problems like near collisions and runway interference occur far more frequently than the government previously recognized.

NASA gathered the information under an $8.5 million safety project, through telephone interviews with roughly 24,000 commercial and general aviation pilots over nearly four years. Since ending the interviews at the beginning of 2005 and shutting down the project completely more than one year ago, the space agency has refused to divulge the results publicly.

Just last week, NASA ordered the contractor that conducted the survey to purge all related data from its computers.

The Associated Press learned about the NASA results from one person familiar with the survey who spoke on condition of anonymity because this person was not authorized to discuss them.

A senior NASA official, associate administrator Thomas S. Luedtke, said revealing the findings could damage the public's confidence in airlines and affect airline profits [emphasis added].

Heaven forbid if the airlines profits were hurt because people could make informed decisions. That's not the capitalist way!

Raising our kids to be sheep

One of the side-effects of the utterly moronic "Zero Tolerance" policies of many schools and governments is that it is teaching our kids to be sheep, devoid of moral sense or an understanding of consequences. What else did we expect to happen when we teach our children that taking a butter knife to school is as worthy of punishment as taking a shotgun?

From Berkeley County, Amber Dauge was expelled from school for accidentally taking a butter knife to school:

"I know I made a really stupid decision but I don't think I should be expelled for it," Amber Dauge said.

Amber says that stupid decision was taking a butter knife to school. She ran out of the house to meet the bus while making a sandwich, when she realized she had the knife. She put it in her bookbag, then she put it in her locker at Goose Creek High school. She forgot it was there until a few weeks later when the knife fell out of her overstuffed locker.

"A kid behind me yelled out a comment that I was going to stab someone with the knife and everyone started laughing and the teacher saw it," Amber told us.

You got that everybody? Taking a butter knife to school is "a really stupid decision".

(Putting aside that it was hardly a decision as such, just a spur of the moment thing.)

No.

Voting for a political party that plans to strip you of your legal protections is "a really stupid decision". Taking a third mortgage on your house to buy shares in a company selling paper clips on the Internet is "a really stupid decision". Putting weed killer in a Coca-Cola bottle and then storing it in the kitchen is "a really stupid decision". Using a lit match to look inside your car's petrol tank is "a really stupid decision".

Kicking kids out of school, destroying their chances of getting educated and condemning them to a life as an angry, bitter second-class citizen is "a really stupid decision".

Taking a butter knife to school is so trivial it doesn't even show up on the radar. As sins go, taking a butter knife to school is up there with such heinous crimes as scratching your ear or eating a boiled egg on Tuesdays.

Supporters of Zero Tolerance actually consider the injustice it results in as a plus. The so-called reasoning behind that is that because the rule is inflexible, those at risk of breaking the law are forced to take even unreasonable steps to avoid breaking the rule.

This is, not to put too fine a point on it, crazy talk. This puts obedience to the law above the consequences of the law. It is no virtue to obey bad laws, although it may be the path of least resistance. Any law that requires unreasonable steps to avoid breaking it is an unreasonable law, and an unreasonable law is unjust and therefore a bad law.

Some might argue that if the consequences of the act are sufficiently terrible, then unreasonable steps to avoid it might be needed; but that's simply stupid. By definition, if the steps required to avoid breaking the law are unreasonable, either they cause more harm than breaking the law, or they are impossible or impractical to do. Otherwise they would be reasonable!

If obeying the law causes more harm than the thing it is trying to prevent, then we would be better off without the law (it's a bad law); and if it is impractical or impossible to obey the law, then no matter how much you punish people the law will still be broken. A law that can't be obeyed is also a bad law, because we're better off without it: we'd still suffer the consequences of the bad actions, but we'd avoid the needless and pointless punishments. Whipping a baby for wetting itself doesn't stop it wetting itself, and it harms the baby for no good reason. Needless to say, not only are bad laws useless, they can even be counter-productive: people can be driven into socially harmful behaviour.

Whether they are Politically Correct liberals, or conservative god-botherers like "Louisa" who wrote:

I think the School did the right thing the school's laws were made to be obeyed by all students. If the school was to compromise for one, {after all even a butter knife could kill someone}then the next incident? the student would expect the same. Compromise is not the answer. God Is!

they're all moral midgets who shouldn't be trusted with deciding what underwear they wear, let alone something important like the education of our children.

"Zero Tolerance" in this case meaning "We're too stupid to be able to apply conscious thought on a case-by-case basis". -- Mike Sphar

Grass jelly

Note to self: it doesn't matter how tasty it looks on the label, or how fascinating and exotic it sounds, grass jelly is not fit for human consumption, no matter what millions of Asians say.

Or maybe it's just that I have a surfeit of yin and need more yang in my diet.

Scrumping for loquats

Some of my favourite fruits are loquats. I have fond memories from my teens of climbing loquat trees on my parents farm and gorging myself on the fruit. Since moving back into the city, it's been very hard for me to find them: although there are trees dotted around Melbourne, they have a short season and I haven't seen any greengrocers selling them.


So I was especially pleased when Mrs Impala found a tree overhanging a lane way not too far away, and last Saturday we went scrumping. We collected about two kilos of loquats. Yum!

For those who have never tried them, they are a little larger than cherries, yellow when ripe, with between one and four large seeds. They are mostly sweet, although the skin can be a little tart. The flesh itself has a flavour vaguely like a cross between lychee and cantelope.
